Choose a pile of bones or a corpse of a M or S Humanoid within range. The target becomes an Undead creature: a Skeleton if bones or a Zombie if a corpse.
On each of your turns, you can take a Bonus Action to mentally command the undead if it is within 60' (you can command multiple at the same time). If no commands, the creature takes the Dodge action and moves only to avoid harm.
The creature is under your control for 24 hrs, after which it stops obeying any command you've given it. To maintain control of the creature, you must cast this spell on the creature again before the current 24-hr period ends.
You animate or reassert control over two additional Undead creatures for each spell slot level above 3. Each of the creatures must come from a different corpse or pile of bones.
